"[It was a] journey that started soon after we arrived in Washington when they set off for their first day at their new school," Michelle explained. "I will never forget that winter morning as I watched our girls, just seven and 10 years old, pile into those black SUV's with all those big men with guns. And I saw their little faces pressed up against the window, and the only thing I could think was, ‘What have we done?’"

"At that moment I realized that our time in the White House would form the foundation for who they would become, and how well we manage this experience could truly make or break them," she added. "That is what Barack and I think about every day as we try to guide and protect our girls through the challenges of this unusual life in the spotlight."

The 52-year-old stateswoman also addressed the multitude of divisive and hateful attacks her husband has faced during his time in the Oval Office, explaining how the couple had to teach their kids how to "ignore them who question their father's citizenship or faith."

"How we insist that the hateful language they hear from public figures on TV does not represent the true spirit of this country. How we explain that when someone is cruel or acts like a bully you don't stoop to their level," she continued. "No, our motto is when they go low, we go high. With every word we utter, with every action we take, we know our kids are watching us."

She went on to say that she and her husband take the same approach to their jobs as president and first lady "because we know that our words and actions matter not just to our girls, but to children across this country."

Michelle also addressed the historic nature of her husband's legacy, both as a successful politician and as the nation's first black president, saying that theirs is "the story of generations of people who felt the lash of bondage, the shame of servitude, the sting of segregation, but who kept on striving and hoping and doing what needed to be done so that today I wake up every morning in a house that was built by slaves. And I watched my daughters, two beautiful, intelligent, black young women, playing with their dogs on the White House lawn."

Michelle then brought her powerful oration around to address the point of the DNC, explaining that this election is not about left or right, Republican or Democrat, but instead, it's about "who will have the power to shape our children for the next four or eight years of their lives."

"I am here tonight because in this election there is only one person who I trust with that responsibility, only one person who I believe is truly qualified to be president of the United States, and that is our friend, Hillary Clinton," she said, endorsing the presumptive Democratic presidential nominee.

"I trust Hillary to lead this country because I've seen her lifelong devotion to our nation's children," she concluded. "Not just her own daughter, who she has raised to perfection, but every child who needs a champion."

After her evocative speech, President Obama took to Twitter to adorably praise his wife, writing, "Incredible speech by an incredible woman. Couldn't be more proud & our country has been blessed to have her as FLOTUS. I love you, Michelle."

Incredible speech by an incredible woman. Couldn't be more proud & our country has been blessed to have her as FLOTUS. I love you, Michelle.

Recently, Michelle joined James Corden for an amazing installment of "Carpool Karaoke" where they rocked out with Missy Elliott and talked about what she's going to miss the most about living in the White House. Check out the video below.
